The President, who made his fortune buying and developing real estate, has said he will be able to cut the cost of the wall after the Department of Homeland Security estimated it would cost up to £17.2billion ($21.6billion).

During his world changing election campaign the Republican firebrand claimed the wall would require a payout of just £9.6billion ($12billion).

But the political heavyweight kept his cards close to his chest, refusing to reveal how he would manage to negotiate a lower price for the controversial wall along the southern border with Mexico.

Mr Trump claimed last month he had managed to negotiate down the price of roughly 90 F-35 jets

In a statement on Twitter he wrote: "I am reading that the great border WALL will cost more than the government originally thought, but I have not gotten involved in the design or negotiations yet.”

"When I do, just like with the F-35 FighterJet or the Air Force One Program, price will come WAY DOWN!"

Mr Trump claimed last month he had managed to negotiate down the price of roughly 90 F-35 Joint Strike Fighter jets from Lockheed Martin.

It comes as the President considers a brand new executive order on immigration

However, defence analysts claim the discount hailed by Trump as a success was in line with what had already been put forward by Lockheed and would apply to other countries committed to the same program.

It comes as the President considers a brand new executive order on immigration after a US appeals court upheld the suspension of his controversial travel ban.

Among those options are an entirely new immigration plan, or the possibility of rewriting the existing order.
